The company that worries me more is Genewize. I am a physician and they sent a representative to my office. They test 12 SNP for common enzyme disorders like MTHFR for $200 and then for $100/month they formulate personalized vitamins that are supposed to optimize the function of your deficient enzymes. They were unable to show me any evidence in a peer reviewed articles. When is the FDA going to start regulating the supplements industry?
